Confused

So I got a positive pregnant test and called my doctor who ordered a blood test. I got my results... hcg is low and so is progesterone... they are giving me pills for the low progesterone and repeat labs on Monday...

What are the chances that this ends in a healthy pregnancy????

I went through a miscarriage and then 2 back to to back chemicals.... I dont think I can handle if this baby doesnt stick....☹😭😞
